Supply Voltage
RST
C2
Reset: The device's RST pin can be used to clear the internal address counter.
When CLK is LOW, a HIGH-to-LOW transition on RST resets the address counter
to zero, and the first bit of memory will be output on I/O after the falling edge of RST.
Also, the RST pin can be used to place the device in low power standby mode by
placing RST in HIGH logic state and both PGM and FUS in LOW logic state. While
RST is HIGH, the internal address counter will not be incremented with CLK.
CLK
C3
Serial Clock and Address Control: This is the device data clock pin. It is used to
clock data bits into and out of the device. It also increments the internal address
counter.
FUS
C4
Security Fuse Pad: This pin is used by card issuer to personalize the device before
releasing it to the customer. When FUS pin is driven to logic HIGH state and the
state of the internal security fuse is HIGH (not blown), the issuer can personalize
the entire content of the memory with successful Security Code (SC) validation.
When FUS pin is driven to logic LOW state and the state of the internal security fuse
is HIGH (not blown), the full protection of the memory is enabled and the security
features of the device can be tested by the issuer. After the device personalization
is completed, the issuer should blow the internal security fuse to logic LOW state
so that the full protection of the memory will always be enabled regardless of the
state on FUS pin. (Refer to IS23SC1604 Security Levels and also Blowing Internal
Security Fuse.)

I/O
C7
Serial Data Input and Output: This pin is where the data bit is shifted in and out
of the device when a clock pulse is applied to CLK pin.
PGM
C8
Programming Control: This pin is asserted HIGH to initiate memory write or erase
operation.
